Description
Technical field
The utility model relates to the high-voltage great-current inductance, is specifically related to a kind of encapsulation type inductance.
Background technology
Along with science and technology development, the application of inductance in circuit is very general, and its kind, shape also are tending towards variation, and precision is higher, and outward appearance is more beautiful, and is more safe and reliable; But a lot of inductance can works under high pressure conditions, but can not be in operate as normal under electric current and the transient high-current impact greatly; Under the big electric current or the impact of transient high-current, inductance even with the situation of blasting; For example inductance is worked in 20～30kV, average current hundreds of ampere, high-tension circuit more than transient current two kiloamperes.At present, inductance satisfies the demand of big electric current or transient high-current impact usually through the diameter that increases the inductance coiling when using; But this way can be brought the problem of two aspects, the one,, the diameter that increases the inductance coiling will certainly increase the manufacture difficulty of coil, and the structural strength of annex on the inductance has been proposed very high requirement, and the manufacture difficulty of inductance increases; On the other hand, the volume and weight of inductance all can increase greatly, all brings constant for manufacturing, assembling, transportation; No matter be its processing and manufacturing; Still material cost all can increase greatly, if produce this inductance in enormous quantities, with the manufacturing cost that increases considerably inductance.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of volume little, and manufacture difficulty is little, and low cost of manufacture is safe and reliable, can satisfy the encapsulation type inductance of high voltage, big electric current/transient high-current impact work requirements.
To achieve these goals, the technical scheme of the utility model employing is:
Said encapsulation type inductance comprises the skeleton that is wound with copper coil on protective cover and the surface, and it is inner that said skeleton is located at said protective cover, and said skeleton is concentric with said protective cover; On said protective cover, be provided with the line outlet that the copper cash that is used for copper coil stretches out; In protective cover, be respectively equipped with busbar on the two ends of said skeleton, the two ends of said copper coil are stuck on the said busbar; On the two ends of said protective cover, be provided with end casing, between said end casing and said busbar, be provided with pressing plate, pressing plate is connected with said busbar; On said protective cover, be provided with the insulation pin; Between said protective cover and said end casing contact position, said insulation pin and said protective cover contact position, said skeleton and end casing and be provided with the cured epoxy resin layer between said skeleton outer surface and the protective cover inwall.
Said skeleton and protective cover are the epoxy cylinder structure of lamination type.
On said skeleton surface, be provided with the draw-in groove of being convenient to the copper coil coiling.
Said pressing plate is connected through sunk screw with said busbar.
The technical scheme that said encapsulation type inductance adopts compared with prior art, has the following advantages:
Said encapsulation type inductance, at first, through safe and reliable version being set and being convenient to the structural member of processing and manufacturing; Secondly,, make that the encapsulation type induction structure is firm, not only can satisfy the high-pressure work demand, can satisfy the work requirements of big electric current and transient high-current simultaneously through the encapsulation type structure Design; Last said encapsulation type inductance, the structural member volume of choosing is little, weight is lighter, and is safe and reliable, and the processing and fabricating cost is low.
